The Losers have returned to Derry, but something's wrong; they don't remember the traumatic events of their childhood.

The Losers' Club reunites for a dinner together at a Chinese restaurant as they recall the oath they made that if Pennywise were to ever return, they would come back to stop it. James McAvoy ("Split", upcoming "Glass") stars as Bill, Oscar nominee Jessica Chastain ("Zero Dark Thirty", "Mama") as Beverly, Bill Hader (HBO's "Barry", "The Skeleton Twins") as Richie, Isaiah Mustafa (TV's "Shadowhunters: The Mortal Instruments") as Mike, Jay Ryan (TV's "Mary Kills People") as Ben, James Ransone (HBO's "The Wire") as Eddie, and Bill Skarsgård returning in the seminal role of Pennywise.

Bill Skarsgard plays Pennywise in It Chapter Two. While the child actors that graced the big screen two years ago will definitely be back, this new film will focus on the so-called "adult Losers", with James McAvoy, Jessica Chastain and Bill Hader joining the cast.

Over 4,500 gallons of fake blood were used during one particular scene, most of it on her. Chastain said that she even encouraged her friend Muschietti to use more.

Chapter 2 trailer was released on Thursday as it featured the 42-year-old Oscar-nominated actress fearing for her life as she was drowning. And don't even get us started on the spiders. The movie follows on from 2017's hugely successful Stephen King adaptation and it hits theaters in September 2019.
